Parapluie (French for "Umbrella") is a computer virus used by Sangvis Ferri, first deployed against Griffin & Kryuger in 2062 as part of Plan Paraluie. After infecting a Tactical Doll, Parapluie acts as a backdoor to spy on the carrier data, install extraneous programs, and, on order of Elisa, completely convert them into a Sangvis T-Doll by rewriting their Neural Cloud from Zener to OGAS protocol. Many Sangvis-controlled computer terminals were trapped with Parapluie to infect any T-Doll making contact with them. Elite T-Dolls infected by Parapluie include SMG UMP45UMP45 , AR ST AR-15ST AR-15 and AR M16A1M16A1 , though Parapluie did not take hold in all of them. 16LAB has successfully developed countermeasures against Parapluie.
The first T-Doll selected by Sangvis Ferri to be infected was AR ST AR-15ST AR-15 , as Elisa believed her upright personality would make her easier to bargain with and have her deliver AR M4A1M4A1 to Sangvis. AR-15 was infected after coming into contact with a trapped terminal while evading Sangvis forces after the raid on Safe House 3 in 2062.
Griffin first learned about Parapluie through the intel recovered by AR Team in Safe House 3, but the virus in AR-15 was used to locate Griffin's secret base and stage an attack on the meeting planned to organize a strategy against Plan Parapluie in an effort to kill Berezovich Kryuger. AR-15 was discovered to be the source of the leak due to increased data traffic and Griffin detained her. AR-15 decided to turn the virus against Sangvis Ferri, deactivated all her communication modules to stop its spread and escaped Griffin's custody to infiltrate Sangvis databases with the authorizations granted by the virus' presence and find intel about its design, which she left in storages for Griffin to recover. Five days after the attack, Griffin deployed Squad 404 against a signal jammer suspected to have been installed for Plan Parapluie in Area S06, but the jammer was an infected decoy meant for Griffin units, and SMG UMP45UMP45 was infected with a dormant form of Parapluie. As AR-15 was roaming Area S08 for intel, Dreamer leaked information about a server site to direct her to a specific terminal and install a jamming module in her system, creating a large signal jamming area and slowing Griffin's advance into Sangvis territory. AR-15 was declared KIA after she blew up the building containing her and one of Elisa's dummies, but she was saved by Task Force DEFY. After this, she kept all her digital transmission modules deactivated in order to contain Parapluie, preventing her the use of the Zener network to control dummies and exchange data and relying only on analog radio for long-range voice transmission. Though the infection had been too mild to take over her neural cloud, her prime directive of protecting AR M4A1M4A1 had been destroyed.
In the aftermath of the Area S08 battle, AR Team and all T-Dolls suspected of being infected were quarantined in Area S05 for further screening as 16LAB established countermeasures against Parapluie. The first T-Doll known for carrying such countermeasures is SMG RO635RO635 , who could detect Parapluie-infected terminals by sensing the pattern of the virus remote control signal and neutralize it before accessing the terminal, as well as perform local counter-jamming. Much like AR-15, 16LAB also used the virus as a mean to infiltrate Sangvis Ferri networks. This modified strain was used by AR M16A1M16A1 to access top secret files at Sangvis's Base 0 and help stabilize M4A1's neural cloud after her encounter with Elisa, but in doing so she subjected herself to an unrepairable amount of the virus and her neural cloud was overwritten by Sangvis Ferri. M16A1 (Boss) later appeared to fight against Griffin, saying she was glad she could use her capacities to their fullest after breaking free of the limitations of human control.
As part of the joint assault on Sangvis Ferri by Griffin and KCCO in 2063, the military pledged high-tier active defense systems and cyberwarfare countermeasures from their central servers in order to counter any Parapluie deployment, arguing that a virus developed by a private company could not match the capabilities of their infrastructure. KCCO deployed interference neutralizers to counter Parapluie's jamming and pushed quickly toward Sangvis' stronghold, leaving Griffin forces to guard the equipment. When the military troops were close enough, Elisa put her plan into action and issued a general order to use Parapluie at its full extent. In doing so, Elisa accessed a military server trapped with their own counter-virus meant to establish control over her.
At the same time, Squad 404 was deployed to recover the data extracted by M16A1, but the Parapluie virus planted into UMP45 a year prior betrayed their presence to Dreamer and Destroyer. Sending Destroyer close enough to connect with UMP45's virus, Dreamer relayed Elisa's general order to convert her neural cloud. However, none had predicted that UMP45, as an old Sangvis Ferri electronic warfare T-Doll, was able to swap her neural cloud from Zener to OGAS protocol, interrupting Parapluie's effects. Moreover, this enabled her to tap into Sangvis Ferri's resources to counter their own virus as long as she used the OGAS protocol. Realizing the situation, Dreamer opted to use Parapluie's command authorizations to melt UMP45's neural cloud with Sangvis' offensive firewalls. UMP45 was narrowly able to survive by disconnecting her neural cloud.
After the military's retreat and the disappearance of their counter-jamming capacities, Parapluie spread into all available networks, jamming transmissions and taking control of military units left behind as well as Griffin T-Dolls deep enough in the signal. This forced the Commander to accept the offer of Task Force DEFY for help in recovering AR Team. DEFY relied on AR AK-12AK-12 's EW capabilities, and to a lesser extent AR AN-94AN-94 's, to break through the jamming and maintain communications during their operation, while the Commander's forces relied on foot messengers like SMG MP7MP7 to establish transmissions from outside the jamming zone. KCCO's plan to take over Elisa ultimately failed when OGAS performed its own counter-attack and nearly destroyed KCCO's servers.
Dandelion later discovered that Persica designed the neural clouds of AR M4 SOPMOD IIM4 SOPMOD II and SMG RO635RO635 with strong firewall defenses against incoming OGAS format data, causing a complete system crash in case the dataflow becomes too heavy to defend against. This makes them impervious to Parapluie infection.
